<h2 id="rzahqadvrf">Advantages</h2>
<p>Windows environment on iSeries&trade; provides most of the capabilities of
running Microsoft&reg; Windows on a PC-based server and provides
the following advantages over other computer systems.</p>
<p><span class="bold">Space savings</span></p>
<ul>
<li>There are fewer pieces of hardware to manage requiring less physical space.</li></ul>
<p><span class="bold">Greater accessibility and protection for your data</span></p>
<ul>
<li>An integrated Windows server uses iSeries disk storage, which is generally more
reliable than PC server hard disks.</li>
<li>You have access to faster iSeries tape drives for integrated server backups.</li>
<li><img src="delta.gif" alt="Start of change" />You can back up the entire Windows server as part of your iSeries server backup. This allows you to recover a failed server much faster
and easier than with typical file level recovery from Windows.<img src="deltaend.gif" alt="End of change" /></li>
<li>Integrated servers implicitly take advantage of superior data protection
schemes which exist in i5/OS&trade; such as RAID or drive mirroring.</li>
<li><img src="delta.gif" alt="Start of change" />Typical integrated server configurations have storage space
data spread across more iSeries disk drives than would be configured
in stand-alone (non-integrated) Windows server installations. This can frequently
provide better peak disk I/O capacity, since each server is not constrained
to few dedicated drives.<img src="deltaend.gif" alt="End of change" /></li>
<li><img src="delta.gif" alt="Start of change" />You can add additional disk storage to integrated servers without
shutting down the server.<img src="deltaend.gif" alt="End of change" /></li>
<li>It is possible to gain access to DB2&reg; UDB for iSeries data through an enhanced Open Database
Connectivity (ODBC) device driver using iSeries Access. This device driver enables
server-to-server applications between integrated servers and i5/OS.</li>
<li>You have the ability to use an integrated server as a second tier in a
three-tier client/server application.</li>
<li><img src="delta.gif" alt="Start of change" />Virtual networking does not require additional LAN hardware
and provides communications between iSeries logical partitions, Integrated xSeries&reg; Servers (IXSs), Integrated xSeries Adapters (IXAs), and iSCSI HBAs.<img src="deltaend.gif" alt="End of change" /></li></ul>
<p><span class="bold">Simplified administration</span></p>
<ul>
<li>User parameters, such as passwords, are easier to administer from i5/OS. You can create users and groups and enroll them from i5/OS to integrated
servers. This makes updating passwords and other user information from i5/OS easy.</li>
<li>Your computer system is less complicated thanks to the integration of
user administration function, security, server management, and backup and
recovery plans between the i5/OS and Microsoft Windows environments. You can
save your integrated server data on the same media as other i5/OS data and restore
individual files as well as i5/OS objects.</li></ul>
<p><span class="bold">Remote management and problem analysis</span></p>
<ul>
<li>You can sign on to i5/OS from a remote location and shut down or restart your
integrated server.</li>
<li>Since you can mirror integrated server event log information to i5/OS you can remotely
analyze Microsoft Windows errors.</li></ul>
<p><img src="delta.gif" alt="Start of change" /><span class="bold">xSeries server attached with an Integrated xSeries Adapter (IXA) or iSCSI HBA</span><img src="deltaend.gif" alt="End of change" /></p>
<ul>
<li>You have considerably more flexibility in configuring a full size xSeries than you have in configuring an IXS, an xSeries on a card.</li>
<li>Full size xSeries models are released more often, meaning that you
can get the most up-to-date Intel&reg; processors and other hardware.</li>
<li>More PCI feature cards are available for full size xSeries servers
than for IXSs.</li></ul>
<p><img src="delta.gif" alt="Start of change" /><span class="bold">IBM&reg; BladeCenter&trade; server attached via an iSCSI host
bus adapter</span><img src="deltaend.gif" alt="End of change" /></p>
<ul><img src="delta.gif" alt="Start of change" />
<li>Dense IBM BladeCenter packaging</li>
<li>New IBM BladeCenter models are released more frequently than IXS.</li><img src="deltaend.gif" alt="End of change" /></ul>
<p><span class="bold">Multiple servers</span></p>
<ul>
<li>Microsoft Cluster service allows you to connect multiple
servers into server clusters. Server clusters provide high-availability and
easy manageability of data and programs running within the cluster.</li>
<li>Without using LAN hardware, servers and logical partitions running on
the same iSeries have high-performance, secure virtual networking communications.</li>
<li>You can run multiple integrated servers on a single iSeries. Not only
convenient and efficient, this also gives you the ability to easily switch
to another up-and-running server if the hardware fails.</li>
<li>If you have multiple integrated servers installed on your iSeries, you can
define their Windows domain roles in a way that will simplify user enrollment
and access. For example, you might want to set up one of these servers as
a domain controller. Then you only have to enroll users to the domain controller
and users can log on from any Microsoft Windows machine on that domain.</li>
<li>An iSeries server's optical and tape drives can be shared with integrated
servers running on the iSeries.</li></ul>
<p><img src="delta.gif" alt="Start of change" /><span class="bold">Hot spare support</span><img src="deltaend.gif" alt="End of change" /></p>
<ul><img src="delta.gif" alt="Start of change" />
<li><img src="delta.gif" alt="Start of change" />Server integration and storage virtualization provide innovative
options that can enhance the reliability and recoverability of the Windows
server environment.<img src="deltaend.gif" alt="End of change" /></li>
<li><img src="delta.gif" alt="Start of change" />If the Windows server hardware fails, you can quickly and easily
switch the server's configuration to another hot spare xSeries server or IBM BladeCenter server without restarting your iSeries server. This may reduce the overall
number of PC servers needed to provide increased availability.<img src="deltaend.gif" alt="End of change" /></li>
<li><img src="delta.gif" alt="Start of change" />Hot spare support also adds flexibility by enabling one spare
server to be used to protect multiple production servers.<img src="deltaend.gif" alt="End of change" /></li><img src="deltaend.gif" alt="End of change" /></ul>
